Construction Update on Routes VT-100 and VT-100A

The Vermont Agency of Transportation (AOT) is using accelerated construction to improve VT-100 in Plymouth and VT-100A, which spans Plymouth and Bridgewater.

DATE: September 24, 2021

VT-100 TRAFFIC IMPACT: VT-100 will remain closed between Route 4 and VT-100A (see map). The road will not reopen by September 26 due to construction delays. Detour signs and message boards are in place to direct traffic. Please travel with caution. 

CONSTRUCTION ACTIVITIES: This week the contractor completed installation of culvert 114, and has been removing existing culvert 115. Next week, the contractor will install new guardrail at culvert 114, and continue cleaning off the ledge at culvert 115 so that a concrete foundation can be installed.The existing culvert 115 has been exposed for future concrete foundation installation.
LOCATION: VT-100 in Plymouth between VT-100A and Route 4.


VT-100A TRAFFIC IMPACT: There will be alternating lanes of travel at active construction work during construction hours (6:00 am until 6:00 pm). Travel will be managed by both flaggers and Automated Flagger Assistance Devices. Stop on red, go on flashing yellow, and mind the gate! 

REMINDER: During the VT-100 closure (see above), VT-100A is the dedicated detour route. Please plan your travel accordingly.

CONSTRUCTION ACTIVITIES: This week, Pike Industries continued paving and guardrail operations. During next week, this work will continue and plug joints will be installed where the roadway meets the bridges. Alternating lanes of travel will be in place during these activities.
